The FactChoeung Ek is the site of a former orchard and mass grave of victims of the Khmer Rouge killed between 1975 and 1979 - about 17 km south of Phnom Penh, Cambodia is the best-known of the sites known as The Killing Fields, where the Khmer Rouge regime executed over one million people between 1975 and 1979. This mass graves containing 8,895 bodies were discovered at Choeung Ek after the fall of the Khmer Rouge regime. Many of the dead were former political prisoners who were kept by the Khmer Rouge in their Tuol Sleng detention center. After the discovery of the site in 1979, the Vietnamese transformed the site into a memorial and stored skulls and bones in an open-walled wooden memorial pavilion. Eventually, these remains were showcased in the memorial's centerpiece stupa, or Buddhist shrine. The stupa has acrylic glass sides and is filled with more than 5,000 human skulls. Some of the lower levels are opened during the day so that the skulls can be seen directly.(source: wikipedia)

In order to save bullets, the executions were often carried out using poison, spades or sharpened bamboo sticks, axes and other killing toopls. In some cases, the children and infants of adult victims were killed by having their heads bashed against the trunks of Chankiri trees, and then, they were thrown into the pits alongside their parents. The rationale was to stop them growing up and taking revenge for their parents' deaths. To suppress the noise and moaning of the victims, they hanged loudspeakers on the tree and played local Khmer music at a loud volume on them. And to hide the smells out from the body lying in open pits, they sprayed chemicals.

More than a million people were killed and buried by the Khmer Rouge regime, during its rule of the country from 1975 to 1979, immediately after the end of the Cambodian Civil War (1970–1975).
